BACKGROUND ART

In general, plate-shaped support wall structures, as known from DE-OS197 48 192.2, have honeycomb structures and are made of paper or pulp.According to such a honeycomb structure, the cover plate is supported byvertical middle walls, so the structure is stable and the weight issmall. Plate-shaped support wall structures are generally used fordoors, internal structures, and outdoor market structures, etc. However,such plate-shaped support wall structures are weak to humidity.

Further, a sandwich support wall structure is described in DE-OS 19 22693.8. The sandwich support wall structure has a honeycomb structurecomposed of two cover plates and walls disposed between the cover platesto make compartments. In this support wall structure, the two coverplates are connected by welding or soldering and the soldering materialis distributed uniformly up to the edges of the compartments, so thecover plates are strongly connected to the honeycomb structure.Accordingly, the edges of the compartments are strong, but the walls aresupported by the cover plates, so the stability of this hard honeycombstructure fully depends on the cover plates and the stability at thecore part of the sandwich support wall structure is small enough to benegligible. Further, there is another defect that the manufacturing costis high and synthetic materials cannot be used.

A invention, titled “Lightweight construction element in the form of ahollow body contoured honeycomb structure”, has been proposed inPCT/DE2000/01683, but according to this structure, plates are molded,the molded plates undergo precision machining such as cutting, and aprocess for bonding the semi-finished products that have undergone theprecision machining for assembly is performed, so a large amount ofmanpower and work time is required.

BEST MODE

A multiple support structure A according to a first embodiment of thepresent invention includes: a top support plate 1 that has a pluralityof rectangular projective islands separated by lattice-shapedprojections 12 protruding in the shape of a go board, and protrudingupward in the opposite direction to the lattice-shaped projections 12;an intermediate reinforcing plate 2 that has upward projectiveinsertions 22 protruding in a shape corresponding to the rectangularprojective islands 11 to be inserted in the rectangular projectiveislands 11 of the top support plate 1, has top grooves 21 formedlaterally and longitudinally between the upward projective insertions 22to insert the lattice-shaped projections 12, has downward projectiveinsertions 22′ formed in the same shape as but in the opposite directionto the upper projective insertions 22 in spaces diagonally adjacent tothe upper projective insertions 22, and has bottom grooves 21′ formedlaterally and longitudinally between the downward projective insertions22′; and a bottom support plate 1′ that has a plurality of rectangularprojective islands 11′ separated by lattice-shaped projections 12′protruding in the shape of a go board, and protruding downward in theopposite direction to the lattice-shaped projections 12′ to be fitted onthe downward projective insertions 22′.

The top support plate 1 and the bottom support plate 1′ are arranged inopposite direction, but have the same shape, so the top support plate 1will be mainly described hereafter.

The rectangular island protruding upward on the top support plate 1, asshown in FIG. 1B, is separated by the lattice-shaped projections 12, aflat cross projection 13 is formed on the top of the rectangular island11 on the top support plate 1, and slopes 14 are formed toward the edgesof the rectangular island 11 at the sides of the flat cross projection13, so the rectangular island 11 has eight slopes 14 inclined upward.

In the intermediate reinforcing plate 2, the upward projectiveinsertions 22 protruding upward are separated by the top grooves 21formed laterally and longitudinally between the upward projectiveinsertions 22 and receiving the lattice-shaped projections 12, flatcross projections 23 protruding in a shape corresponding to the flatcross projections 13 except the edges are formed on the upwardprojective insertions 22 to fit the flat cross projections 13 on the topof the rectangular islands 11, and slopes 24 inclined toward the edgesare formed at the sides of the flat cross projections 23, so that eightslopes 24 inclined upward are formed at each of the upward projectiveinsertions 22 and the four outer sides of the upward projectiveinsertions 22 are formed in a diamond shape when the upward projectiveinsertions 22 are seen from above. Accordingly, the upward and downwardprojective insertions 22 and 22′ protruding upward and downward,respectively, on the intermediate reinforcing plate 2 are formed suchthat the diamonds are repeatedly and alternately formed.

Therefore, the downward projective insertions 22′ protruding downward onthe intermediate reinforcing plate 2 are formed in a direction oppositeto that of the upward projective insertions 22, but have the same shapeas the upward projective insertions 22, so they are not described indetail.

In this embodiment, the top and bottom support plates 1 and 1′ are usedin pairs, have the same configuration, and are coupled to both sides ofthe intermediate reinforcing plate 2, respectively, but only one of thetop and bottom support plates may be used, if necessary.

The top support plate 1 is formed by molding plastic resin into athickness of about 0.7 mm in this embodiment, but the thickness of thesynthetic resin is just an example and it may be possible to mold thesynthetic resin into a thickness of 0.3˜2 mm, depending on the use orstrength. In particular, it may be possible to use not only syntheticresin, but a paper plate made of pulp or metallic plate, and a combinedconfiguration in which the intermediate reinforcing plate 2 is made ofsynthetic resin and the top and bottom plates 1 and 1′ are paper plateor metallic plate may be used for convenience.

Lattice-shaped grooves 15 are formed on the top of the top support plate1 to correspond to the lattice-shaped projections 12, and a pair offinish plates 3 having a plurality of projective insertions 31 that isinserted in the lattice-shaped grooves 15 may be fixed to finish the topof the top support plate 1, but flat finish plates 3 may be attached tothe tops of the flat cross projections 13.

Projective insertions 31 are longitudinally formed on one of the finishplates 3 fixed to the top support plate 1 and projective insertions 31are laterally formed on the other finish plate 3, so applied weight canbe distributed.

The finish plates 3 are made of synthetic resin, but the material is notlimited thereto and stone or metal may be used.

The intermediate reinforcing plate 2 is disposed between the pair of topand bottom support plates 1 and 1′ in this way.

The intermediate reinforcing plate 2 is inserted between the top andbottom support plates 1 and 1′, the top grooves 11 are arranged tocorrespond to the gaps of the lattice-shaped projections 12 of the topsupport plate 1, the upward projective insertions 22 are sequentiallyformed between adjacent top grooves 21 and protrude as high as thelattice-shaped projections 12, and as shown in FIG. 3, the downwardprojective insertions 22′ are formed in the opposite direction betweenthe upward projective insertions 22 in the same shape as the upwardprojective insertions 22.

The downward projective insertions 22′ protruding in the oppositedirection, but in the same shape as the upward projective insertions 22are formed on the opposite side to the upward projective insertions 22of the intermediate reinforcing plate 2, and the upward projectinginsertions 22 and the downward projective insertions 22′ are formed inthe opposite directions, but in the same shape to fix the top and bottomplates 1 and 1′ disposed opposite to each other. Accordingly, they aredifferentiated by marks ″, ′, and ″, but are given the same number andhave the same function.

In this embodiment, the intermediate reinforcing plate 2 is formed bymolding synthetic resin with a thickness of about 0.4 mm. The thicknessof the synthetic resin is just an example and it may be possible to moldthe synthetic resin into a thickness of 0.3˜2 mm, depending on the useor strength. In particular, it may be possible to use not only syntheticresin, but a paper plate made of pulp or metallic plate, and a combinedconfiguration in which the intermediate reinforcing plate 2 is made ofsynthetic resin and the top and bottom plates 1 and 1′ are paper plateor metallic plate may be used for convenience.

The operational effect of the multiple support structure A according tothe first embodiment of the present invention having this configurationis described in detail hereafter.

First, an adhesive is applied to the coupling portions of the top andbottom support plates 1 and 1′ and the intermediate reinforcing plate 2to be assembled and the lattice-shaped projections 12 of the top andbottom support plates 1 and 1′ are inserted into the grooves 21 and 21′on the top and bottom of the intermediate reinforcing plate 2. When thelattice-shaped projections 12 of the top and bottom support plates 1 and1′ are inserted in the top and bottom grooves 21 and 21′ of theintermediate reinforcing plate 2, they are in contact with the bottomsof the flat cross projections 13 on the top of the rectangular islands11 of the top and bottom support plates 1 and 1′, whereby the tops ofthe flat cross projections 23 are brought in contact with each other.

As described above, in the multiple support wall structure A accordingto the first embodiment of the present invention, the top and bottomsupport plates 1 and 1′ and the intermediate reinforcing plate 2 arecombined by fitting the lattice-shaped projections 12 of the top supportplate 1 into the top and bottom grooves 21 and 21′ of the intermediatereinforcing plate 2, in which the upward and downward projectiveinsertions 22 and 22′ of the intermediate reinforcing plate 2 areinserted in the rectangular islands 11 of the top and bottom supportplates 1 and 1′, and the flat cross projections 13 and the flat crossprojections 23 of the intermediate reinforcing plate 2 are in surfacecontact with each other. Accordingly, many surface contact areas aremade, so even if large load is applied to the multiple support wallstructure A, the load is distributed by the many surface contactportions and the structure can resist large load.

That is, in detail, according to the multiple support wall structureaccording to the first embodiment of the present invention, as shown inFIG. 4A, the lattice-shaped projections 12 of the top and bottom supportplates 1 and 1′, which are separate parts, and the top and bottomgrooves 21 and 21′ of the intermediate reinforcing plate 2 are insurface contact with each other; the slopes 14 of the rectangularislands 11 of the top and bottom support plates 1 and 1′ and the slopes24 of the upward and downward projective insertions 22 and 22′ of theintermediate reinforcing plate 2 are in surface contact with each other;and the flat cross projections 13 on the tops of the rectangular islands11 of the top and bottom support plates 1 and 1′ are in surface contactwith the flat cross projections 23 of the upward and downward projectiveinsertions 22 and 22′ of the intermediate reinforcing plate 2, sosurface contact is made at many portions. Accordingly, even if largeload is applied to the multiple support wall structure A, the load canbe distributed by the surface contact portions. As described above, themultiple support wall structure A according to the first embodiment ofthe present invention is assembled only by fitting the top and bottomsupport plates 1 and 1′ and the intermediate reinforcing plate 2 withoutspecific machining, so installation is simple and installation time isshort. Accordingly, manpower for installation is considerably saved, sothe installation costs are also reduced.

As shown in FIG. 4B, for example, a plurality of multiple support wallstructures A according to the first embodiment of the present inventionis each assembled in a size of 1 m width and 1.5 m length and laterallysequentially arranged at the positions indicated by solid lines.Further, a plurality of multiple support wall structures A is laterallyarranged to overlap the above arrangement at the positions indicated bytwo-dot chain lines at the middle portion, so indefinite expansion canbe sequentially achieved to acquire necessary spaces. Accordingly,limits in installation space can be removed and they can be installed ina wide area.

The finish plates 3 are fixed to the top and bottom support pates 1 and1′ by the lattice-shaped grooves 15 on the top and the bottom of the topand bottom support plates 1 and 1′. When the finish plate 3 having thelongitudinal projective insertions 31 is fixed to the upper supportplate 1 and the other finish plate 3 having the lateral projectiveinsertions 31 is fixed to the lower support plate 1′, the strength isfurther increased, so even if large load is applied, it is possible toresist the load by distributing the load. Further, as shown in FIG. 5B,when the flat finish plates 3 can be bonded to the top and bottomsupport plates 1 and 1′ by applying an adhesive to the flat crossprojections 13, the multiple support wall structure A can be more easilymanufactured.

The multiple support wall structure A according to the first embodimentof the present invention having the structure described above isassembled by applying an adhesive, fitting the lattice-shapedprojections 12 in the top and bottom grooves 21 and 21′, and the bondingthem, but as shown in FIG. 6A, when the plates are made of differentmaterials and difficult to bond, it may be possible to more stronglycombined them using bolts 4. Alternatively, it may be possible tocombine the plates by fitting the lattice-shaped projections 12 in thetop and bottom grooves 21 and 21′, fixing them with bolts 4, and thenriveting or welding them. Further, as shown in FIG. 6B, it may bepossible to solder the contact portion between the flat crossprojections 13 of the top and bottom support plates 1 and 1′ and theflat cross projections 23 of the intermediate reinforcing plate 2, withthe lattice-shaped projections 12 fitted in the top and bottom grooves21 and 21′.

FIG. 7A is an exploded perspective view of a multiple support wallstructure according to a second embodiment of the present invention inwhich a center support member 5 is disposed at the center to increasethe strength of the multiple support wall structure, intermediatereinforcing plates 2 are disposed over and under the center supportmember 5, respectively, and finish plates 3 are coupled or bonded to theintermediate reinforcing plate 2, respectively.

In the center support member 5, top rectangular grooves 50 recesseddownward to insert downward projective insertions 22′ on the bottom ofthe intermediate reinforcing plate 2 over the center support member 5are formed on the top, while bottom rectangular grooves 50′ recessedupward to insert upward projective insertions 22 on the top of theintermediate reinforcing plate 2 under the center support member 5 areformed on the bottom of the center support member 5, so the centersupport member 5 has a double-fitting structure with the top rectangulargrooves 50 and the bottom rectangular grooves 50′ arranged in oppositedirections.

The top rectangular grooves 50 of the center support member 5, as shownin FIG. 7B, each have a cross groove 51 at the center, a crossprojection 52 protruding diagonally upward from the cross groove 51, andslopes 53 extending from the cross groove 51 to the cross projection 52.The bottom rectangular grooves 50′ of the center support member 5 eachhave a cross groove 51′ at the center, a cross projection 52′ protrudingdiagonally downward from the cross groove 51′, and slopes 53′ extendingfrom the cross groove 51′ to the cross projection 52′.

Accordingly, the top rectangular grooves 50 on the top of the centersupport member 5 are fitted on the downward projective insertion 22′ ofthe intermediate reinforcing plate 2 under the center support member 5,and the bottom rectangular grooves 50′ of the bottom of the centersupport member 5 are fitted on the upward projective insertion 22 of theintermediate reinforcing plate 2 under the center support member 5. Thatis, the cross projections 52 and 52′ of the center support member 5 andthe top and bottom grooves 21 and 21′ of the intermediate reinforcingplates 2 are in surface contact with each other, while the slopes 53 and53′ of the center support member 5 and the slopes 24 of the upward anddownward projective insertions 22 and 22′ of the intermediatereinforcing members 2 are in surface contact with each other, wherebymany surface contact portions are made. Accordingly, even if large loadis applied to the multiple support wall structure A, the load can bedistributed by the surface contact portions and the multiple supportwall structure A can be made thick by the center support member 5.

The center support member 5 is also made of synthetic resin in the sameway of molding the intermediate reinforcing plates 2.

FIG. 8 is an exploded perspective view of a multiple support wallstructure A according to a third embodiment of the present invention, inwhich a center support member 5 is disposed at the center, intermediatereinforcing plates 2 are disposed over and under the center supportmember 5, respectively, top and bottom support plates 1 and 1′ aredisposed over and under the intermediate reinforcing plates 2,respectively, and finish plates 3 are coupled to the outer sides of thetop and bottom support plates 1 and 1′, respectively, whereby themultiple support wall structure can be made thick and the strength canbe increased.

When it is required to make the multiple support structure A thicker,the thickness can be increased by doubly coupling couple theintermediate reinforcing plates 2 to the center support member 5, so itis possible to freely adjust the thickness.

FIG. 9 is an exploded perspective view of a multiple support wallstructure A according to a fourth embodiment of the present invention,in which an intermediate reinforcing plate 2 is disposed at the centerand finish plates 3 are fixed to the top and the bottom of theintermediate reinforcing plate 2, so a simple and strong multiplesupport wall structure can be achieved.

FIG. 10 is an exploded perspective view of a multiple support wallstructure A according to a fifth embodiment, in which an intermediatereinforcing plate 2 is disposed at the center and a pair of pyramidalcell support plates 4, which has a plurality of pyramidal cells 41protruding on the top and the bottom, respectively, and lattice-shapedplane 42 on the opposite sides, is coupled to the top and the bottom ofthe intermediate reinforcing plate 2, respectively.

FIG. 11A is an exploded perspective view of a multiple support wallstructure A according to a sixth embodiment of the present invention, inwhich an intermediate inserting member 6 is disposed at the middleportion and the top and bottom support plates 1 and 1′ according to thefirst embodiment are fixed to the top and the bottom of the intermediateinserting member 6.

In the intermediate inserting member 6, as shown in FIG. 11B, aplurality of pyramidal projective cells 60 are laterally andlongitudinally sequentially formed, straight line-shaped projections 61horizontally protruding are formed at the middle portions of thepyramidal projective cells 60, grooves 62 are formed at both ends ofeach of the straight line-shaped projections 61, slopes 63 are formed atboth sides of the straight line-shaped projections 61, and pyramid-sidewalls 64 are formed at the edges of the slopes 63 and have a triangularcross section that is smaller at the top. Further, pyramidal projectivecells 60′, which have straight line-shaped projections 61′ protruding inthe opposite direction and formed perpendicular to the straightline-shaped projections 61 are laterally and longitudinally sequentiallyformed at the joints of the pyramid-side walls 64. Accordingly, thepyramidal projective cells 60 having the straight line-shapedprojections 61 are formed on a side of the intermediate inserting member6 and the pyramidal projective cells 60′ protruding in the oppositedirection and having the straight line-shaped projections 61′ formedperpendicular to the straight line-shaped projections 61 are laterallyand longitudinally sequentially formed on the opposite side.

The intermediate inserting member 6 is also made of synthetic resin inthe same way as the intermediate reinforcing plates 2.

Accordingly, when the lattice-shaped projections 12 of the top andbottom support plates 1 and 1′ are inserted in the grooves 62 of theintermediate inserting member 6 over and under the intermediateinserting member 6, the straight line-shaped projections 61 of thepyramidal projective cells 60 are in contact with the bottoms of theflat cross projections 13 of the rectangular islands 11 and the slopes63 are in contact with the slopes 14, thereby completing the multiplesupport walls structure according to the sixth embodiment of the presentinvention of which the strength is increased by a plurality of adjacentwalls.

In a multiple support wall structure A according to a seventh embodimentof the present invention, as shown in FIG. 12, an intermediate insertingmember 6 is disposed at the middle portion, the top and bottom supportplates 1 and 1′ are fixed to the top and the bottom of the intermediateinserting member 6, respectively, and flat finish plates 3 are fixed tothe outer sides of the upper and lower support plates 1 and 1′,respectively, so a simple and strong multiple support wall structure canbe achieved.

According to the multiple support wall structures A of the presentinvention, the strength is larger and the weight is smaller than plywoodor other plates and a high insulation effect can be achieved by manyspaces in the multiple structures. Accordingly, the structures can beused for vertical walls of a building requiring insulation such as aglasshouse, so they can provide high insulation effects. Further, thestructures can provide high soundproof or sound-blocking effects, sothey can be used for not only the walls of buildings, but also forseparation walls in airplanes or ships, and can be used for variousother purposes. Furthermore, the structures can be directly assembledwithout specific post-processes, so installation time, manpower forinstallation, and installation costs are reduced.
